Invisible watermarking embeds ownership details into digital files without affecting their quality, while blockchain provides a tamper-proof, decentralized ledger for verifying ownership. Combining these two technologies creates a powerful system for protecting digital content against misuse and theft. Here’s how:
- Invisible Watermarking: Adds undetectable ownership marks to files, resistant to edits or compression.
- Blockchain: Records cryptographic hashes and metadata, ensuring ownership data is secure and unalterable.
- Smart Contracts: Automate rights management, monitor usage, and streamline enforcement.
This dual-layer approach strengthens content security by embedding ownership data in the file and storing it securely on the blockchain. It’s already being used in industries like entertainment, education, and e-commerce to combat piracy and verify authenticity. For example, platforms like ScoreDetect integrate these technologies to protect content efficiently, offering tools like automatic watermarking and blockchain-based verification certificates.

How Blockchain Improves Invisible Watermarking Systems
Pairing blockchain technology with invisible watermarking creates a synergy that strengthens traditional watermarking systems. Together, they provide tamper-resistant verification, automated workflows for protection, and permanent ownership records, all functioning seamlessly to safeguard digital content.
Embedding and Storing Watermark Data
The process starts with embedding invisible watermarks into digital content using proven algorithms. In September 2024, researchers Xiaochen Yuan and Chan-Tong Lam introduced a Blockchain-Watermarking Mechanism (BWM) that uses the Enhanced Fast Walsh Hadamard Transform (FWHT) algorithm. This method embeds ownership information into images without compromising their visual quality [1].
Once a watermark is embedded, the system generates a cryptographic hash of the watermarked file, acting as a unique digital fingerprint. This hash, along with metadata, is stored on the blockchain. For large files like videos or high-resolution images, only the cryptographic hash and the file’s IPFS address are recorded on the blockchain, while the actual files are stored off-chain. This approach avoids the impracticality and high costs of storing large files directly on the blockchain.
As Yuan and Lam explain:
"The combination of watermarking and blockchain technology perfectly satisfies our requirements [for protecting image copyright information without compromising privacy, and avoiding reliance on third-party platforms]." [1]
For video content, the system employs perceptual hash functions to analyze key frames. These functions generate hash values that remain consistent even after compression or format changes, ensuring reliable watermark verification without needing the original video file [2].
Permanent Records for Ownership and Verification
By integrating watermarking with blockchain’s verification capabilities, creators gain a powerful tool to combat piracy. Once watermark data is recorded on the blockchain, it becomes virtually unalterable. Each block contains an encrypted hash of the previous block, along with timestamps and transaction details, creating a secure and permanent chain of evidence.
A practical implementation of this concept was demonstrated in March 2024 by researchers using Hyperledger Fabric and IPFS. Their system stores original remote sensing image data in a private IPFS network while recording critical metadata – such as Content Identifiers (CIDs) and SHA256 hash values – on the Hyperledger Fabric blockchain. This ensures both secure storage and reliable metadata verification [3].
Dr. Yujie Liu from the Aerospace Information Research Institute highlights the security benefits:
"The immutable nature of blockchain, coupled with its decentralized storage across nodes and encryption techniques, offers high security, making it a potential solution for protecting the integrity and authenticity of remote sensing image while safeguarding against unauthorized access and data tampering." [3]
To verify content ownership, users can simply compare the hash of a file with the immutable record on the blockchain. If the content has been tampered with, the hash will differ, immediately signaling unauthorized modifications.
Automating Content Protection with Blockchain
One of the most transformative aspects of blockchain-enhanced watermarking is the use of smart contracts. These self-executing programs automatically trigger actions when specific conditions are met, streamlining content protection workflows.
In June 2025, Vinitha G and her team developed a "Digital Copyright Protection and Tracking System" that demonstrates this automation. Their platform combines a React-based interface with MetaMask for Ethereum login. When a user uploads a file, the system automatically applies an invisible watermark encoding the user’s Ethereum wallet ID, timestamp, and unique file hash. The upload event is then recorded on the blockchain, and detailed access logs are maintained on the server [6].
Smart contracts handle tasks like access control, watermark application, verification, and logging automatically. This eliminates manual processes while maintaining security and providing transparent audit trails.
A more advanced example is the BEWSAT framework, introduced in August 2025 for industrial visual inspection systems. This system uses a GAN-based watermarking model to embed authenticity proofs into images, encrypts the watermarked files, and stores them on IPFS. The unique Content Identifier (CID) and metadata are recorded on the Ethereum blockchain via smart contracts, enabling any party to verify the content’s authenticity without relying on third-party authorities [4].
IBM emphasizes the efficiency of smart contract automation:
"Smart contracts facilitate the seamless automation of transactions, enhancing efficiency and accelerating real-time processes. When predefined conditions are met, they automatically trigger the next step, reducing the need for manual intervention." [7]
This automation extends to anti-piracy efforts. While these systems don’t directly issue takedown notices, they provide robust tools for evidence collection and verification. Immutable blockchain records serve as undeniable proof in legal disputes, and automated tracking helps identify unauthorized content use across the internet.
Platforms like ScoreDetect take this a step further by capturing content checksums on the blockchain. Their workflows integrate with over 6,000 web applications through Zapier, simplifying the entire process – from watermarking to enforcement actions. This streamlined, tamper-resistant approach lays the foundation for the enhanced security and ownership solutions discussed next.
Key Benefits of Blockchain-Based Watermarking
The fusion of blockchain and watermarking technology brings a powerful layer of protection to digital content. By combining these two systems, creators can address some of the most pressing challenges in safeguarding their work.
Clear Proof of Ownership
Blockchain provides a reliable way to establish ownership with immutable, timestamped records. These records serve as legally sound evidence, making it nearly impossible for others to dispute or tamper with ownership claims. For example, platforms like Blockai use blockchain timestamps to document the creation of new works, while Mediachain Lab tracks the origins of stock photos to ensure proper credit is given to original creators [10][13].
What makes this system even more effective is the use of public-key cryptography, which allows creators to sign their work for instant and verifiable authentication. As Inês Botelho, Head of Content Marketing at the Cardano Foundation, puts it:
"Blockchain enhances traditional authentication methods, providing a secure and transparent solution for enterprises and individuals" [11].
This approach outperforms traditional verification methods by offering instant, tamper-proof validation.
Better Security and Tamper Protection
Blockchain’s architecture is inherently resistant to tampering, making it an ideal match for safeguarding watermark data. For instance, the PoWBWM system, introduced in January 2025, combines a Proof of Work consensus mechanism with a convolution attention model to improve tamper detection in High Dynamic Range images [8]. Similarly, the BEWSAT framework uses a GAN-based watermarking method and blockchain to store encrypted images and metadata on an IPFS network, with all changes tracked through smart contracts. Any attempt to alter the data triggers a change in the Merkle root hash, signaling tampering [4].
Consensus mechanisms like Practical Byzantine Fault Tolerance (PBFT) further bolster security by requiring agreement from the majority of network nodes before any record changes are accepted [9]. The BFLIPR framework showcases how blockchain’s unchangeable nature and smart contracts can secure private watermark parameters, ensuring data remains consistent and protected [9]. This layered security approach also supports automated anti-piracy tools.
Stronger Anti-Piracy Measures
Blockchain-powered watermarking systems simplify and automate piracy detection and response. With smart contracts, protective actions can be triggered automatically upon detecting unauthorized use, streamlining the anti-piracy process. The permanent and traceable nature of blockchain records also strengthens creators’ positions in legal disputes over intellectual property [5].
Platforms like Ujo Music demonstrate how blockchain empowers creators to self-publish their work while retaining control over their data and marketing [13]. Efficiency is another key advantage. For instance, BlockGuard uses 88% less storage space on secondary systems compared to traditional methods [14], while optimized platforms like Hyperledger Fabric can process up to 20,000 transactions per second, enabling real-time monitoring and enforcement [15].

From tackling piracy in entertainment to safeguarding intellectual property in academics, this technology is making waves in revenue recovery and content protection.
Media & Entertainment
Piracy remains a massive challenge for the entertainment industry, with losses exceeding $50 billion in 2023. Music streaming platforms alone lose around $2.7 billion annually due to unauthorized distribution [19][20]. A striking example of blockchain watermarking’s effectiveness comes from 2024, when musician Zara Laine used the technology to trace 300 pirated copies, recovering $28,000 and cutting piracy by 72% [20].
"Blockchain introduces new layers of transparency and control that make piracy harder to carry out and easier to track", says Michael Willson of the Blockchain Council [16].
This system embeds unique digital fingerprints into each distributed copy of content. If pirated material appears online, AI-powered detection tools scan platforms to identify watermarked content – even if it has been altered. Adrian Linde, CTO of Xchange Monster, explains:
"The system can provide each viewer with a copy of the content that contains a distinct digital fingerprint, which can immediately be used to locate the original pirated content" [17].
Custos Media Technologies is a prime example of this approach’s scalability, having protected over 4 million movies through their patented blockchain watermarking solutions [18]. Their method combines forensic watermarking with blockchain’s immutable record-keeping, producing evidence suitable for legal action.
Academics and Education
Educational institutions face unique challenges in protecting intellectual property, such as research papers and course materials. Blockchain watermarking offers a reliable way to safeguard academic content while establishing permanent, unalterable proof of ownership through time-stamped records [21][22].
Invisible watermarks can be embedded into digital resources like research papers and course videos. Once uploaded to the blockchain, these assets gain an immutable timestamp that verifies their creation date and ownership. Dr. Xinxin Fan, former Senior Research Scientist at Bosch Research Technology Centre, highlights the benefits:
"Blockchain allows time-stamping in an immutable, tamper-proof way, making plagiarising previously copyrighted material impossible" [17].
By eliminating the need for third-party certification platforms, this decentralized system simplifies ownership verification. Additionally, watermarking technology protects sensitive academic research by embedding copyright information directly into the content, ensuring both security and verifiability [1].
Ecommerce and Digital Business
Online businesses are increasingly battling counterfeiting and issues around digital asset authenticity. The global blockchain technology market, valued at $17 billion in 2023, is expected to skyrocket to over $943 billion by 2032 [23]. Yet, challenges persist – OpenSea reported that over 80% of NFT assets created through their free storefront contract were plagiarized works, fake collections, or spam [24].
Blockchain watermarking addresses these issues by verifying digital asset authenticity. For instance, Digimarc uses invisible digital watermarks to link NFT data with the corresponding digital content securely. Their technology encrypts key details like blockchain IDs, contract addresses, and token IDs, helping marketplaces flag counterfeit NFTs and protect creators and consumers alike [24].
Luxury brands are also leveraging blockchain by pairing physical products with NFTs. This approach, highlighted by BigCommerce, offers consumers a transparent way to verify authenticity and trace product origins [23].

Implementation and Best Practices
Setting up blockchain-integrated invisible watermarking requires careful planning and technical know-how. To get the best outcomes, organizations must address infrastructure needs, ensure compliance, and seamlessly incorporate the system into existing workflows.
Technical Setup and Requirements
The first step in building a blockchain watermarking system is choosing the right platform. Ethereum is a popular choice due to its decentralized ledger and smart contract capabilities. Organizations also need to select a consensus algorithm, like Proof-of-Work or Proof-of-Authority, depending on their network’s energy efficiency and connectivity requirements [1]. For secure and decentralized storage, the Interplanetary File System (IPFS) is often used to house watermarked assets and encryption keys. Meanwhile, smart contracts handle tasks like ownership registration, transaction requests, and access control [1].
A study conducted in September 2024 demonstrated the integration of blockchain with advanced techniques like the Fast Walsh Hadamard Transform (FWHT) for embedding watermarks, along with Arnold Transform for scrambling [1]. To interact with the system, users need tools such as a crypto wallet (e.g., MetaMask) and libraries like ethers.js for decentralized application (DApp) interactions.
"The new blockchain technology is suited for addressing the issue of long-term preservation and security authentication without the need for a third-party platform", notes ScienceDirect [1].
Once the architecture is in place, the focus shifts to ensuring privacy and compliance.
Privacy and Compliance Considerations
To address privacy concerns and meet regulatory requirements, it’s best to store only content checksums on the blockchain rather than the full digital assets. This approach protects sensitive data while still allowing for ownership verification through blockchain’s tamper-proof records. It also aligns with copyright laws and data protection regulations, which is especially critical in international contexts.
By adhering to data minimization principles, organizations can use hash values and timestamps to prove ownership without exposing unnecessary details. Regular security audits and rigorous testing of smart contracts are essential to identify and fix vulnerabilities before deployment.
Workflow Automation and Integration
Technical setup alone isn’t enough – integrating the system into daily operations is key to making it effective. Modern blockchain watermarking systems are built as decentralized applications (DApps), which allow content owners and users to interact with blockchain and watermarking features seamlessly [1].
"The proposed method is implemented with a Decentralized App (DApp). The DApp makes use of a Smart Contract as the intermediary between Owner and Requester for image trading requests, authorization, deposit, and transmission for the images and the secret keys used for data encryption and image scrambling", explains ScienceDirect [1].
To work smoothly with current digital asset management systems, these platforms need API compatibility and process orchestration. Tools like ScoreDetect illustrate this by offering integrations with over 6,000 web apps via Zapier. These integrations automate tasks such as capturing content checksums and generating verification certificates, eliminating manual steps.
Batch processing is another valuable feature, enabling the automatic embedding of watermarks and blockchain registration for entire content libraries. Real-time monitoring systems can track protected content online, using AI-powered tools to scan for unauthorized use and initiate takedown procedures when necessary.
For WordPress users, plugins can automate the process by capturing and timestamping every published article. This creates verifiable blockchain proof of ownership without disrupting publishing routines. To optimize performance, it’s important to manage blockchain transaction costs and processing times. Techniques like efficient queuing systems and layer-2 solutions can help reduce fees while maintaining the system’s security, ensuring a robust defense against piracy.
